Codec C Series - Dual Display Option

Unanswered Question
Mar 9th, 2011

Hi Community,

In the Codec C Series, is possible to connect 2 LCDs simultaneous without dual display licence?

I just need to project the conference in both LCD's.

Best Regards,

Pedro Vasques

I have this problem too.

I just tried it on my C20; the second HDMI port is not active (I don't have the DD option).  Doesn't matter if I have xconf video monitors set to single/dual or dualpresentationonly.  This doesn't surprise me at all; why would they have an optionkey for it if it worked by default? 

(Of course, if you always want the same display in two places, just use a HDMI video splitter).

In additional to the previous answer, both video ouptuts available on the C40 are enabled by default from software version TC4.x. Without the Dual Display option, you'll get the same content on both screens as desired.

Hi All,

Thanks for the information.

Now, my doubt is clear enlightened.

On any device, you could always add a HDMI splitter with 1 input and 2 (or more) outputs.
